Na, I wasn't ready for anything like that back then. That was like 14 - 15 years ago. It freaked me out a little at the time.
My first trip to Thailand was with my American GF, who's father lived and worked in Thailand. He took us out to Patpong red light district and into a bar full of hotties. He was buying them all drinks and they were all over me and my GF (who is bi), and everyone is making out, I'm groping tits, good time. Though, her dad wasn't participating other than buying drinks.
So after a while her father leans over and asks me which one I like the most. I point out the one I had been making out with, total stunner. He laughs and says something along the lines of, "That's a man. They are all men. Let that be a lesson to you about Thailand, that nothing is as it seems here. Don't ever forget that."
It was a great lesson and I never forgot it, even though on my 2nd trip to Thailand I ended up in bed with one.
On the very first trip, I had noooooo idea what a ladyboy was. Foreign concept. So that was my introduction. On the second trip, I was aware, but I still really didn't get it and was able to be fooled.
Now I live in Thailand and produce ladyboy porn. Funny how that worked out.
